The Flame Thrower and Mortar are as you might expect. One is the suppressing weapon that also ends up actually forcing units to move, hurting their shooting, if they want to avoid being ranged in on. A Flame Thrower is just dangerously awesome and quite the fearsome weapon on the tabletop.

The Ampulomet was a defensive and indeed almost homebrew weapon that was filled with chemicals to smash over the enemy. It was quite the cruel weapon and used extensively in the defence of Leningrad and Stalingrad.
